4415.4. Error Codes TableNote:“O” - Frequency measured and fan speed fixed.The memory data of error code is erased when the power supply is cut off, or press the Auto Switch until “beep” sound heardfollowing by pressing the “CHECK” button at Remote Control.Although operation forced to stop when abnormality detected, emergency operation is possible for certain errors (refer to ErrorCodes Table) by using Remote Control or Auto Switch at indoor unit. However, the Remote Control signal receiving sound ischanged from one “beep” to four “beep” sounds.Abnormality / Protection control AbnormalityJudgementEmergencyoperation Primary location to verifyDiagnosisdisplayH00 No abnormality detected — Normal operation —H11 Indoor / outdoor abnormalcommunication> 1 min. after startingoperationIndoor fan operationonly• Internal / external cable connections• Indoor / Outdoor PCBH14 Indoor intake air temperature sensorabnormalityContinue for 5 sec. — • Intake air temperature sensor(defective or disconnected)H15 Outdoor compressor temperature sensorabnormalityContinue for 5 sec. — • Compressor temperature sensor(defective or disconnected)H16 Outdoor Current Transformer opencircuit— — • Outdoor PCB• IPM (Power transistor) moduleH19 Indoor fan motor merchanism lock — — • Indoor PCB• Fan motorH23 Indoor heat exchanger temperaturesensor abnormalityContinue for 5 sec.
